Abstract: Waveform data stored in an external memory are transferred from the external memory to an internal waveform memory and read out from the waveform memory to reproduce a tone. Transfer instruction is generated each time data readout from the waveform memory progresses by one page, and the transfer instruction is registered into a transfer queue. Thus, in response to the transfer instruction from the queue, the waveform data are read out on page by page from the external memory and stored into the waveform memory. The external memory also stores therein error correction code attached per page. As the waveform data are transferred from the external memory to the waveform memory, an error is detected using the error correction code, and if the error is correctable, the error is corrected. If the error is uncorrectable, volume of a tone being generated is rapidly attenuated, or a warning is issued.
